If you need help in quitting tobacco, consult a doctor for stop-smoking products and other strategies for quitting.


Alcohol drinking has been linked to various cancers of the digestive system including the mouth, throat, voice box, colon, liver and rectum. Excessive alcohol consumption causes damage to the cells, and this is more prominently noticed in cases of mouth and throat cancers. Excess alcohol can also disrupt hormonal levels in the body. It is okay to have it in very small quantities but better to avoid it altogether.


Obesity is one of the factors that increase the risk of cancer. Excessive fat in the body interferes with the healthy, regular functioning of the body. When there is excessive fat in the system, hormonal levels are imbalanced, insulin levels are affected and there is increased inflammation in the body. Regular exercise strengthens the immune and improves the body’s ability to stay healthy.


Exposure to sunlight is crucial for the absorption of Vitamin D however between the time period of 10 A.M to 4 P.M, the sun’s rays could do more damage than harm. During this period, the sun’s UV rays are very strong which increase the risk of skin cancer. If you must go out, wear protective clothing like hats/sunglasses/full-length outfits.


Engaging in sexual practice with unknown or risky partners increases the chance of developing sexually transmitted diseases like HIV or AIDS. This also increases the risk for cervical cancer, cancer of the genital organs, and anal cancer. Infected needles are also a source of transmission of disease – before allowing a needle to enter the body, one must ensure the needle is a fresh, unused and disinfected piece.

Simple lifestyle changes can make a difference. Consider these cancer-prevention tips. Along with this regular self-exams and screenings for various types of cancers can increase your chances of discovering cancer at an early stage, when treatment is most likely to be successful.
